Best Practice on Junit: Always set your fields to null on tearDown

This was a surprise to me today. Just wanted to share it thourgh a small blog entry, so maybe others are also going through the same thing.

Say you have this test:


public class MyTest extends TestCase
{

Server server;

public void setUp()
{
server = new Server();
}

public void testOne() throws Exception
{
System.gc();
Thread.sleep(1000);
}

public void testSecond() throws Exception
{
System.gc();
Thread.sleep(1000);
}

public void testThird() throws Exception
{
System.gc();
Thread.sleep(1000);
}
}


JUnit will hold one instance of MyTest for every method being executed. So if Server is a heavy weight object you will end up with three instances in the memory, until all the test methods on this class are executed.

So, as a best practice on unit tests aways set big objects such as server, connections or anything lilke that to null on a junit test.

JBoss Messaging 2.0 beta 4 is released

We just released Messaging 2.0 beta 4, and it' s ready to download.

I' m pleased with the progress we are making, and we are excited about what we are doing.

We still have work to do but we are very confident about the quality of the work we are doing.

Look at the documentation and you will know what I' m talking about.

Fedora 11 finally got me...

I have been using a competitor distribution for very long (about 2 years) even though I work for RedHat / JBoss, just because it was easier. I couldn' t figure out how to do a few things.

I have tried to come to Fedora a few times.. and I could never feel comfortable.


But Fedora 11.. that' s really nice. I would say I don't even feel I'm on Linux. I'm feeling very comfortable like using my wife's Mac OS X :-)

The WebCam works, wireless... video resolution.. even Skype... everything smooth.

It could be also the Lenovo T500 behaves really well with Linux.. but still... Fedora 11 has got me.

I' m a Fedora user from now on :-)

Everybody Loves Lula!

I just love my president! Maybe he is also wearing a JBoss shirt?

This picture was taken at FISL

Speaking as a brazilian citizen, we had so many highly educated presidents before him, however this government as far as I know has promoted open source in a much better scale than any other previous government.

It is really nice seeing the government promoting open source there.
